Why Choose HDCVI (High Definition Composite Video Interface)?
1.HDCVI is a solution for megapixel high definition applications, featuring non-latent long-distance transmission at a lower cost. The technology offers two specifications: 1080p (1920×1080) and 720p (1280×720).
2.HDCVI is an over-coaxial-cable analog HD video transmission standard, allowing long-distance HD transmission at a lower cost to meet the requirements for a complex and large installation.With no new cabling or IP hassle required, HDCVI is one option for upgrading existing systems from standard definition to high definition, offering longer transmission via coaxial cable and lower total cost.
3.Transmitting data over 500m over a coaxial cable can be realized, depending on the cable selected. Cable 75-3 and 75-5 are recommended for transmissions within 500m, cable 75-5 and above for over 500m. Connectors and welding process also affect the transmission distance.
4.HDCVI composites video, audio, and control signals together and then transmits them over one coaxial cable, simplifying installation.
